What is the primary consideration in determining what type of backflow prevention to install?

• A. Cost of installation
• B. Degree of hazard
• C. Size of the plumbing system
• D. Age of the existing system

Answer: (B)

The primary consideration in determining what type of backflow prevention to install is the degree of hazard. This is crucial because the main goal of backflow prevention is to protect the public water supply from contamination or pollution. Different situations present varying levels of risk; therefore, understanding the degree of hazard associated with specific contaminants or the potential for backflow is essential for selecting the appropriate type of backflow prevention device. For instance, high-hazard applications, such as those involving chemicals, require more robust devices like reduced pressure zone (RPZ) assemblies, which provide a higher level of protection. In contrast, lower-hazard scenarios might only need a simpler device, like an atmospheric vacuum breaker (AVB). This focus on hazard assessment ensures that water systems are adequately protected, particularly in environments such as hospitals, laboratories, or industrial settings where dangerous substances may be present.
